PSP?

Never had a PSP or played it before, but I'm interested only because of FFT. Know some things, but not really.

I want to get a white PSP (Japan), but is it worth it? Yes, I have a DS, and don't tell me not to get the PSP just because it's this generation's Game Gear in spirit.

I know that UMD movies are region locked, but that was born a dying format. How easy is it to bypass, and where can I go to do so? Just wondering, in case I get any free movies.
What can't the PSP emulate, and what does it emulate but poorly?
By default, will the language in the PSP menus and the games be Japanese only, or can I toggle with it?
The PSP I'm interested in is suppose to have a universal adapter, so that should be fine playing (and charging) in the US or where ever I vacation in?

If there's anything else I should know about getting a white Japanese PSP, or just the PSP in general, let me know.

Ok, Let me explain.

PSP CAN emulate PERFECTLY the following consoles/portables.

-all old consoles before Nintendo-
Nintendo
Super Nintendo
Sega Genesis
Gameboy
Gameboy Advance
Playstation
PSP(1)

Now, The Nintendo 64 DOES work on the PSP, but it's no where near perfect yet. Perfect means it can run games at full speed. Wait maybe a year and a nintendo 64 emulator for psp at full speed should be out.

(1)You can also play PSP games on your PSP. I mean as in, you don't have to buy them. You can download a PSP ISO and put it on your memory stick, and play it from there. I have about 12 PSP games on my computer, and maybe 5 PSP games on my memory card.

-UMD movies are region locked-
This doesn't matter. In the PSP, you can trigger a mode that allows you to free the region lock off any UMD. But why buy an UMD? You can just download the movie!!

Here are a few helpful sites for better information:

I believe I covered all..The only part part about all this is downgrading.. There is literally endless possibilities you can do with your psp that people do not know yet. This is why I sold my DS for a PSP. PSP with being hacked SUCKS.
